When refering to evidence in academic writing, you should always try to reference the primary (original) source. That is usually the journal article where the information was first stated. In most cases Physiopedia articles are a secondary source and so should not be used as references. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article).

Introduction[edit | edit source]

LASER means Light Amplification from Stimulated Emission of Radiation.Laser is created by specific process within the laser device to cause the controlled emission of radiation in form of light.[edit | edit source]

Production of Laser[edit | edit source]

Laser device is made up of an optical cavity or chamber that contains active medium for which laser is named.The chamber has mirrors on either end that are perfectly parallel to each other within a single wavelength of light.One of the mirror is partially open.Electricity or energy is added to the medium which excites it.The active mediums atoms are reflected back and forth across the mirrors within the chambers.this causes more excitation of atoms within the medium.Laser light is then emitted through the partially reflective end of mirror.The light production occurs in the following steps:[edit | edit source]

1.Electron is pumped to a higher energy level.[edit | edit source]

2.Pumping level is unstable so the electron quickly jumps to a slightly lower energy level.[edit | edit source]

3.Electron relaxes to a lower energy state and releases a photon.[edit | edit source]

4.Light and an electron in an excited energy level produces two photons of same wavelength and phase.[edit | edit source]

5.Mirror reflects the photons.[edit | edit source]
